Hi

Changing the branch is possible , but its kinda require real hard work and commitment. U 'll need to focus hard coz its nt just JEE, nw u need to compete with the JEE qualified students. U need to be in the top 20 students from the institute to get ur desired branch, and if u r concerned about the best of branches then Computers , ECE , Chemical etc are good.
